发明名称 Hydrau-Linear Automatic Bicycle Transmission
摘要 One aspect of the present invention includes a transmission that includes a cylindrical housing that includes a plurality of parts. The internal parts rotate in unison with the drive shaft, and the centrifugal force created by the rotation of the cone shaped impeller pushes the fluid throughout the transmission. The fluid pressure is used to change the gear ratio from low gear to high gear, and vice versa.
